The stabilisation of rock faces, cuttings and slopes utilises a wide variety of techniques such as the application of rock bolts or dowels. To ensure a practical design and ongoing safety of these slopes and cuttings, a sound knowledge of geological structure, rock mechanics and hydro geology must be applied when selecting the best solution.

Optimization of the catch bench design using a genetic ...

The majority of rockfalls occur due to the existing conditions of slopes, such as back break, fractures and joints. Constructing a berm on the catch bench is a popular method for the mitigation of rockfall hazards in open pit mining. The width of the catch bench and the height of the berm play a major role in the open pit bench design.

A new rating system approach for risk analysis of rock slopes

 · Abstract. In this paper, an approach is presented to analyze the stability risk of rock slopes based on a new rating system. Three factors are used to estimate the risk level of rock slopes: (1) failure probability, (2) element at risk rating, and (3) vulnerability rating.

On civil projects, rock cuts must be safe from rock falls and large-scale slope instability during both construction and operation. In open pit mining, where slope heights can be many hundreds of meters, the economics of the operation are closely related to the steepest stable slope angle that can be mined.
